Here we got a full view of Mt McKinley rising above the colorful fall tundra. There is only one road to access the interior of Denali National Park, and visitors cannot drive their own cars in but must travel on Park buses.  The tourist season is short, only from mid-May to mid-September.  The animals here have adapted to the harsh climate in amazing ways.  When the frogs here hibernate,  they are essentially frozen solid, but somehow they revive in the spring.  The Arctic hare has a heart rate of 110 beats per minute in the summer, but during the winter, it falls to 3 beats a minute!
